Azure Cosmos DB integrations for LangChain and LangGraph: vector stores, semantic caches, chat message history, stores, and checkpointers.
Sync classes are importable from langchain_azure_cosmosdb; their async counterparts live in langchain_azure_cosmosdb.aio.
This page contains reference documentation for Azure Cosmos DB. See the docs for conceptual guides, tutorials, and examples.
